Nissan updated all GU Patrols as of 08/2004 with a longer spline main shaft and 5th gear.
This modification was done to prevent them from wearing out the main shaft and 5th gear spline which was found to be to small for the heavy loads that the vehicles where expected to haul.
The new Gearmaster gears have been designed with this improvement in mind.
Early model Nissans with the short spline 5th gear can be fitted with the new gear provided the spline is in good condition.
A shorter spacer which fits between the gear and the circlip on the main shaft is required.
The gears can be fitted with the gearbox in the vehicle, however the transfer case does have to be removed. Installation is relatively simple allowing the job to be undertaken by most mechanical work shops.
